Self-Starting Soliton–Comb Regimes in χ(2) Microresonators

open access: yesPhotonics, 2023
The discovery of stable and broad frequency combs in monochromatically pumped high-Q optical Kerr microresonators caused by the generation of temporal solitons can be regarded as one of the major breakthroughs in nonlinear optics during the last two ...

Laser-Induced Graphene on a Quartz Crystal Microbalance for Humidity Sensing

open access: yesCrystals, 2021
In this study, a simple method for synthesizing graphene layer directly on a quartz crystal microbalance (QCM) using a laser was developed. This laser-induced graphene (LIG) was used for sensing surface to simultaneously measure changes in the adsorbed ...

Soliton blockade in bidirectional microresonators [PDF]

open access: yesOptics Letters, 2020
We report a method to control, disrupt, and restore a regime of unidirectional soliton generation in a bidirectionally pumped ring microresonator. This control, i.e., the soliton blockade, is achieved by tuning the pump frequency of the counterrotating field. The blockade effect is correlated with the emergence of a dark–bright

Fundamental limit of microresonator field uniformity and slow light enabled ultraprecise displacement metrology [PDF]

open access: yes, 2021
We determine the fundamental limit of microresonator field uniformity. It can be achieved in a specially designed microresonator, called a bat microresonator, fabricated at the optical fiber surface.

Coherent coupling of single molecules to on-chip ring resonators

open access: yesNew Journal of Physics, 2019
We report on cryogenic coupling of organic molecules to ring microresonators obtained by looping subwavelength waveguides (nanoguides). We discuss fabrication and characterization of the chip-based nanophotonic elements which yield a resonator finesse in
